Application filed November 11, 1914. Serial No. 871,450.

To all whom it may concern:

Be it known that I, CARL MUnrILnIsnN, a citizen of the United States of America, residing at Chausseestrasse 23, Berlin, No. 4, in the Empire of Germany, have invented new and useful Improved Means for Controlling the Pump or the'Indenter of a Machine for Making Printing-Slugs, of which the following is a specification.

The present invention relates to improved means for enabling the condition in respect of justification of a typographical line composed in a machine for making printing slugs from such lines, to control the metalinjecting pump, or the fiong-indentmg device thereof, whichever that machine may be equipped with.

There are known at the present time two types of machine for making printing slugs from composed lines. One of these composes matrices and spaces into a line; places that line between two jaws fixed at a distance apart equal to the standard length of slug; operatively thickens each spacer till the line is tight, 2'. e. justified; presses a mold for the body of the slug metal-tight against the row of character-forming cavities in the line, the junction of that mold with the said row forming a mold for the slug; and makes a pump inject molten metal into the last mentioned mold till the latter is filled under pressure, thereby casting a printing slug. This type is known as the Morgenthaler and commercially under the trade mark Linotype. The other type substitutes type-dies for matrices; indents a flong by pressing it and the line together, thereby producing a matrix; and casts from the latter in the way just described. Both types are described in the specification of Letters Patent No. 436532 dated September 16th, 1890.

'Experience with the machine of the first type showed that matrices would sometimes jam in the guides which held them while the spacers were being thickened, with the result that the act of thickening failed to justify the line to the standard length, so that it was loose instead of tight when the pump acted and the metal was squirted between the matrices and over the adjacent parts of the machine. Such accidents are now prevented by one of the jaws being movable outward up to the standard length and 091 nected to the pump in such a way that it holds the pump locked until it has been so moved, when, the line being tight, the pump is unlocked and acts. In the case of a machine of the second type, a jammed matrix would prevent justification in exactly the same way as in a machine of the first type, the mischievous result being a badly justified and therefore spoilt indented matrix instead of a squirt of metal.

From the point of View of the present invention, the pump of the first type and the indenter of the second type are the equivalents of each other, because they have the common function of making a counterpart of the characters in the composed line and are the devices to be respectively unlocked, and the difference between a matrix and a type-die becomes immaterial, and either is referred to by the term piece in the subsequent part of this specification and the claims.

The present invention consists in means by which the joint outward movements of both aws is required to unlock the said device. As a result, if a matrix becomes jammed so as to prevent the proper justification of the line, at one side or the other thereof, the casting or forming action cannot take place, and the objections which would otherwise obtain thereby avoided.

The accompanying figures illustrate two preferred constructional forms of the application of it to a machine of the first type.

In them Figure 1 is a plan showing the composed line justified in both directions from the middle of it, both jaws movable and the pump unlocked by the two-jaws acting together; Fig. 2, a detail front elevation of part of Fig. l; and Fig. 3, a plan of another form.

Referring to Figs. 1 and 2, 1 is the metal pot; 2, the pump; 3, its operating lever; 4, the pieces and 5, the spacers of the composed line confined between 7 and 8, the two movable jaws; 9, the so-called vise-top to which the latter are connected to move outward and inward in the direction of the length of the said line; 10, an abutment on the lever 3; 11, a bell crank lever fulcrumed at 12 on the machine frame and normally held by a spring 13 under the abutment 10 to lock the pump 2 out of action, and 14, a lever of the first class fulcrumed at 15 on the macomposed line located therebetween, and device unless both ends of the line are means for expanding the line, the two conmoved outward during the expanding action. 10 fining jaws being arranged to permit each In witness whereof I have hereunto set of the opposite ends of the line to move my hand in the presence of two witnesses.
